But the show, originally set for June 1-2, will be staged during Labor Day weekend, even without the Blue Angels.

“The situation with the Blue Angels and other military participation is out of our control and are a result of decisions made in Washington, D.C.,” said Mike Dunn, director of economic development and governmental affairs at Chicago Rockford International Airport.

“While we are disappointed to have to postpone AirFest, we are optimistic that we’ll put on a quality air show later this year.”

Organizers around the country have pulled the plug on this year’s airshows. Without the drawing power of the Navy Blue Angels or the Air Force Thunderbirds, they’re worried that their shows will flop. That happened in Rockford two years ago: the Blue Angels pulled out and attendance dropped.

Rockford’s plans are to have a scaled-down show in September, featuring vintage “warbird” aircraft and civilian performance teams. They’re rebuilding the show from scratch, Dunn said, and the absence of the military would mean lower costs for the organizers and cheaper tickets for the public.

“There’s a nice opportunity for us to do a different type of event,” he said. “We think there are some very cool private acts and performers out there.

“The redesigned show will give us an opportunity to recognize and honor the strong history and presence that Rockford has contributed to the aviation and aerospace industry.”

Dunn said AirFest organizers have been in touch with the Blue Angels and put in a request for Labor Day weekend that he said was well-received. There are, however, no guarantees.

“Right now our plan is ... to run the show whether the military shows up or not,” Dunn said.

AirFest organizers are offering refunds to ticket-holders.

People who bought tickets online will have their accounts credited, according to an AirFest news release. Those who bought at a ticket outlet will need to visit the place they bought their tickets for a refund.

Tickets bought at Culver’s restaurants need to be brought to the airport, 60 Airport Drive, for a refund.
